Support for block identifiers

[srackham]

Currently, when attempting Smart Action navigation on a link with a block ID (e.g. [[NoteName#^blockID]]) you get prompted to create a file instead of jumping to the block identifier link target.

I'm finding the Obsidian block ID feature very useful especially for inline embedding (transclusion).

See https://help.obsidian.md/links#Link+to+a+block+in+a+note

I suspect this would probably involve quite a bit of work, so maybe an interim measure would be to check for block identifiers in the link and if found flag the user with a "Block identifiers not yet supported" message.

closing these two because they are pretty valuable and should have issues tracking them, but will not be done in a very near future, will be good to add in lsp completion.
